Most torsion bars have adjuster screws or bolts on the bars. When you tighten one side you have to tighten the other side the same amount. If you don't it will make it will make the vehicle sit crooked. So measure both side then tighten the accordly. If you tighten them up to much though you can break them as they are designed to work in a specified range. If you're looking to lift the vehicle check out a proper lift kit.
on the rear cross member where the torsion bars mount there is an adjustment screw
A Dodge Ram does not have torsion bars.
The tundra does not have torsion bars, buy a lift.
Make sure that you have torsion bars.i believe that you coil springs.your best bet is to find a leveling kit to keep a nice ride.
When you crank on the torsion bars you are changing their spring tension.
You must crank the bolts on the torsion bar clockwise to lift the vehicle
If it 4x4 you need to crank the torsion bars so no rubbing happens but you can easily put 285/70R17

The torsion bars run from the lower control arms to a crossmember almost under the seat area of truck. There are adjusting bolts at the end of the bars that push up an arm to lift and lowers to lower. Tightening the bolt lifts the truck and loosening bolt lowers the truck. Please note that if you crank up bars too much this will greatly affect alignment, steering and is hard on the drive axles. If you do lift it a little then you should always have alignment checked afterwards
crank the torsion bars all the way up. This will stiffen the ride and may affect alignment.
Instead of using coil springs on the front suspension torsion bars are used from the lower control arms to the frame ( my 1995 Ford Explorer 4x4 has torsion bars , my dads 73 Dodge Coronet had torsion bars ) If you look at a lower front suspension that has torsion bars you will see the torsion bars going from the lower control arms rearward
